Analysis of Fused Glass Beads

The determination of the light major elements in geological material using XRF of fused borate glass beads in a very accurate and precise method. While the pressed pellet procedure provides good accuracy for the middle energy elements (K through Fe and Ba and Ce) the light elemts (Na, Mg, Al, Si, and P) are only determined accurately using a homogenous glass sample.

Sample bead preparation is automated using a Leco Fluxer, which simultaneously fabricates six beads. Elements determined by this method are NA, Mg, Al, Si, P, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Ba, Ce, and LOI.

As we require prior analysis by pressed pellet to determine S, As and Fe concentrations, a minimum 10 g of -200 mesh sample powder is required for submission.
